Abstract: L'invention concerne un système de traitement de données de mémoire sous forme de variables mémorisées. Ce système comprend au moins un ensemble d'exécution de données (IPU), une mémoire de données commune (DS), un bus de processeur central et un ensemble de fonction (30) servant à manipuler les variables de façon autonome. Chaque variable possède une adresse logique ou une adresse de base et l'ensemble de fonction (30) comprend des moyens de conversion des adresses logiques en adresses physiques. L'ensemble de fonction comprend, de plus, des premiers moyens de mémorisation (1) servant à mémoriser des adresses de mémoire physiques calculées et des deuxièmes moyens de mémorisation servant à mémoriser temporairement et séquentiellement la dernière adresse calculée. Un dispositif de comparaison (JMF) se trouve dans l'ensemble de fonction (30) et sert à comparer les adresses des demandes d'entrée de mémoire à des adresses de mots physiques, en ce qui concerne particulièrement la dernière adresse de mémoire demandée (A4). Quand les adresses sont identiques (A3=A4), les données de mémoire de la première adresse de mémoire demandée sont réutilisées.

Title: Network data access method
Inventor: BURN-THORNTON KATHRYN ELIZABET
IPC: H04L12/70
Filed: 1997-08-14
Abstract: A data item in a data set having a virtual structure, each item having a virtual location, is accessed by the following steps. A target location in the structure corresponding to the data item to be accessed is identified. A current location for the process is identified. The current location is moved through the structure of the data set to the target location, using a routing algorithm. When the current location is the target location, the data item corresponding to the target location is accessed. The same routing algorithm may be used for other processes, and can increase the efficiency of accessing by reducing conflict between access processes.

Filed: 1996-03-22
Abstract: The present invention relates to a particular type of fan-forced positive pressure breathing apparatus, commonly known as Powered Air-Purifying Respirators (PAPRs). In particular the invention concerns monitoring the operation of such equipment. In a first aspect, the invention provides a powered air-purifying respirator which includes data collection means to enable the volume of air drawn through the filter to be determined. In another aspect, the invention comprises a management system for monitoring and analyzing operational data from at least one powered air-purifying respirator.  The management system includes data collection means associated with each respirator to enable the volume of air drawn through that respirator's filter to be determined, and electronic data processing apparatus into which the data collected by the data collection means is uploaded for analysis. The data processing apparatus may be partly situated on-board each respirator in order to enable alarms to be given to the wearers at appropriate times. However, a remote computer system having data processing facilities will be able to store and subsequently display the data collected, as well as enabling more sophisticated analysis.

Title: Cementing plug
Inventor: GIROUX RICHARD LEE
IPC: E21B33/05
Filed: 1996-04-26
Abstract: The invention provides a bottom cementing plug (594) which is releasably attached to a top plug (584) by means of a tubular sleeve (550) and shear pins (553).  Instead of shear pins a shear ring, which may be segmented, and which is integral with the tubular sleeve, may be arranged. The tubular sleeve (550) comprises first openings (565) which are covered by burst plates (570) for allowing cement to pass after having set the plug on the float shoe at the casing bottom. The tubular sleeve (550) may comprise second openings (554) covered by burst plates (555) to allow the cementing process to be performed in case that the top plug has been launched together with the bottom plug.  The invention further provides a dart launching device, where the darts are arranged in a sleeve coaxially with and radially spaced from the housing of the launching device. A  fluid diverter is arranged at the top of the launching device for diverting the fluid into the annular space between sleeve and housing in order to prevent pressure overload on the plungers which hold the darts in place before they are launched.

Patent CA-2221406-A1 (CA)
Inventor: SCHWENDEMANN KENNETH L
IPC: E21B34/04
Filed: 1997-11-18
Abstract: A retainer valve provides increased safety in wellsite operations. In a preferred embodiment, operation of the retainer valve may be responsive to control line pressure or to tubing pressure. The retainer valve response is controlled by several factors, among which are relative tubing and balance line pressures, and axial positions of a number of pistons relative to a tubular J-slot member. If the control and balance lines are disconnected, or otherwise unavailable for operation of the valve, it may still be operated by manipulation of the tubing pressure at the earth's surface. Thus, the valve may be opened in emergency situations in which the control and balance lines are unavailable, but operation of the valve is still needed in order to safely relieve trapped pressure in the tubing string and/or to kill the well, unlatch a subsea test tree, etc. The retainer valve is also useful as a lubricator valve.

Title: Process for the variable limitation of a flat flow channel and process for extracting a mass channel of variable geometry
Inventor: GROSS HEINZ
IPC: B29C48/31
Filed: 1996-09-25
Abstract: The geometry of a flow channel (1) can be varied within wide limits if at least one wall of the flow charmel (1) takes the form of a sheet stack (2) which is pushed from the rear into the channel to a greater or lesser extent by means of adjusters (7). The adjustment may be effected either uniformly over the entire width of the flow channel (1) or only locally at certain points thereof. It is thus possible, while a medium is passing through the flow channel (1), to alter from outside the flow resistance either of the en-tire channel or only at certain points and thus alter the entire mass flow or the mass flow distribution as desired. New processing possibilities are given by the greater flexibility of the sheet stack (2) in relation to solid channel walls.
